Can't start on Debian/GNU Linux

Hi!

Cant start 2.5 using java 6 and 2.6 using java7.

kacper@zbiig:~/bin$ java -jar JCloisterZone/JCloisterZone.jar
Exception in thread "main" java.awt.HeadlessException
at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:207)
at java.awt.Window.(Window.java:535)
at java.awt.Frame.(Frame.java:420)
at java.awt.Frame.(Frame.java:385)

at com.jcloisterzone.ui.Bootstrap.run(Bootstrap.java:92)
at com.jcloisterzone.ui.Bootstrap.main(Bootstrap.java:115)

May I help anything on debug/investigation of this problem?

2.4 works with java 6, but doesn't with java 7.

Greets!

What desktop environment are you using? The error that's being thrown is

Tests whether or not a display, keyboard, and mouse can be supported in this environment.
(from java itself)
